About

The two-necked flask is a commonly used chemical glass instrument, which is divided into straight and oblique, and is widely used in organic chemistry experiments. The multi-port is mainly for complex experimental operations, and can be equipped with more experimental instruments at the same time.

The oblique opening, due to the presence of an oblique angle, can be directly and evenly added to the center of the bottom of the bottle during feeding. The various instruments and equipment on the surface of the bottle are also beveled. Because of the large gap between the shoulders of the bottle and the large gap between the neck and the neck, the installation is easy, and the special small-sized flask is more obvious.

The two-necked flask usually has the appearance of a round neck. It has two ports, can add a variety of reactants at the same time, or add a condensation tube. Its narrow mouth is used to prevent the solution from spilling or reducing the evaporation of the solution, and can be used in conjunction with the rubber stopper to connect other glass equipment. When the solution requires a long time of reaction or heated reflux, it is generally preferred to use the flask as a container. The opening of the flask has no protruding gap like a beaker, and it is easier to flow down the outer wall when pouring the solution, so the glass bottle is usually touched with a glass rod to prevent the solution from flowing down the outer wall. Because the bottle mouth is very narrow, it is not suitable for the glass rod to stir. If you need to stir, you can hold the bottle mouth slightly and turn the wrist to smoothly stir evenly, or use a special mixer. If it is heated to reflux, a magnetic stir bar can be placed in the bottle and heated by stirring the stirrer.
